Michele Bachmann camp: We won't be using full-time pollsters

I broke the news Friday that veteran pollster Ed Goeas had departed the Michele Bachmann campaign, and now her spokeswoman Alice Stewart explains it this way, in a statement to me:

"Ed has played a critical role in shaping the team and our message. Given the changing caucus and primary schedule, we will not be utilizing full time polling consultants and concentrate heavily on retail politics in Iowa. Ed will work on several projects with us this month, then we shift focus to Iowa and he will shift to other projects not associated with the campaign."

It's not clear why having a pollster is mutually exclusive to doing retail politics - other than the cost.
